It depends on the state. Most states do not take a new spouse's income into account when determining the child support amount, so even if the custodial parent remarries, child support amounts are likely to stay the same.
Yes. They are still the child's parent and responsible for supporting their child.
Highly unlikely.
No - the new spouse isn't responsible for other men's children.
In general, no. (I suppose the answer might be different if she married Donald Trump.)
yes..
If they can establish the stepparent as a primary support in a parent/child relationship.
Not automatically, but can be raised as a rebuttable presumption. see links
No. Child support is paid by non custodial parent, not step parent. Income of a New Spouse: Contrary to common belief, Illinois law permits judges to consider the income of a second spouse when establishing or modifying child support awards. The door swings both ways, too. A custodial parent who remarries a well-to-do spouse may suffer a reduction in child support to be paid by the non-custodial parent.19 Likewise, a non-custodial parent who remarries a spouse of substantial means may be required by the court to pay a higher child support than if the marriage had not taken place. http://www.illinoisdivorce.com/family_law_articles/etsblishing_child_support.php
Remarriage should not affect the child support order.
No.The only way that rights can be terminated for that purpose is if mother remarries and step parent legally adopts.
Typically courts will not penalize a child by reducing support payments because a parent has had another child because this is not seen as being in the best interest of the child.
Generally no, though there is a presumption of primary residential custody for the obligee parent. In states like California, the amount of time the obligor parent has the child affects the amount of child support ordered.ClarificationChild support orders and custody orders are separate. Generally, the parent who pays child support pays it to the custodial parent.
